Default Mechanical failure of emitter resitor soldering - tips?

"professional" amp-head apart.
Failure due to inadequate soldering due to heatsinking of the resistor leads
in the first place. I will deform the protruding leads with a pair of worn
out end snips before re-soldering properly.
Other occassions where replacing the resistors and obviously solder was
affected by long-term heat then abraiding back along the traces and doing
long soldering between extended lead length and traces.
For vibration induced problems replacing with ceramic bead insulators
between the resistor and board rather than just flapping about in mid-air.
Any other tips ? particularly maybe tying together somehow particularly off
the board, on end, vibrating / flapping resistors or vibration induced
failure corrective repair in particular

Hi,
Try to find a copy of Mil-spec. training manual for soldering.
